Re: Integrating Apache FOP in an Eclipse RCP app gives IncompatibleClassChangeError

[Amin Ahmad <am...@gmail.com>]

I just ran into the same problem. Ideally, you want Apache FOP bundled as a
separate plug-in, but based on what I've read here, you've scrapped that
approach and moved FOP into the same plug-in as the client code because of
this error.
Keep FOP in a separate plug-in but remove the two jars xml-apis and
xml-apis-ext. When these JARs are present in the FOP plug-ins
classpath, FOTreeBuilder implements the ContentHandler interface defined in
the xml-apis JAR, which leads to the incompatible class change error (why
this should be is baffling, but I figure it has something to do with the way
OSGI handles dependencies). When you remove these JARs it falls back to
using the JDK/Eclipse standard ContentHandler class and the error goes away.

I hope this helps,
Amin
